To all whom it 'may concern Be it known that I, lVILLIAM P.

My invention relates to that class ot' improvements made use ot' forpulverizing the earth, commonly known as square harrows; and

The nature thereof consists in certain modifications in the constructionand arrangement ot the details ot' the same, by means ol' whichdificulties which haveheretoiore attended the use of harrows areobvia-ted, by causing the bars containing` the teeth to actindependently ot' each other.

In theacrompanying drawing, which illustrates my invention and forms apart of the specilication thereof', is represented a perspective viewoi' a harrow with my invention applied thereto.

The construction, operation, and relative arrangement of the componentparts of my invention are as The frame is manufactured of tough andsound timber, and consists ot' two principal parts, A and B, hingedtogether in the manner hereinafter described.

Ihe longitudinal bars C, containing the. teeth, are pivoted at one oftheir ends within metallic rece-pta.- cles or clips, I), rigidly securedby means of bolts or otherwise, to the inner side ofthe end pieces ortransverse bars E.

The said clips are furnished with anges through which the bolts,instelling them to the transverse bar E, pass.

lhe object of pivoting the said ends of the longitudinal bars C, withinthe stationary clips D of crossbar E, is to allow them to vibrate up anddown, adapting them to the irregularities of thegronnd over which theypass.

F F designate two transverse metallic stripsconnecting the oppositeendsof the longitudinal bars C together by means ot' screw-bolts, H H,passing,y through apertures, j; ont in the said strips.

Ihe said screw-bolts pass loosely through the aperturesf, for thepurpose ot' allowing that end of the longitudinal bars (l which theyenter, tofreely lvibrate, in the manner and for thepurpose described, incon, nection with the pivoted ends of said bars.

Upon the inner end of one ot' the strips F is formel an'eye, 1t", intowhich lits or enters a hook, Ii, formed on the inner end of the otherone ot' the said strips,

thus hinging one end of the frames or parts A and B together, theopposite end ot' the said frames or parts being hinged together by meansof metallic clips, c and y, the one having a bolt or screw, e', with nutpassing through tho other, and the llatter embraced by the former.

The two parts A and B of the harrow being thus hinged together, eitherpart thereot` may be lifted, in order to discharge weeds, roots, orother obstructions.

Having thus described my invention, I will proceed to indicate what Iclaim and desire tosecnre by Letters Patent, in the following clause:

I claim- 'lhe arramgement of the longitudinal bars O, rnetallic clips D,transverse bars E, hinges e e' g and 'i It, metallic strips F, bolt-SH,and apertures ff, constructed and operating substantially as 'describedand shown. l
